A member of a race cursed by the god Apollo. They cannot be out in daylight and they must live on the blood of each other. On their 27th birthday, they die a slow and painful death over the course of a twenty-four hour period unless they decide to turn Daimon and prey on human souls. So long as the human soul is alive inside them, they can live. The moment the soul expires, they die. Therefore, they are always trying to find new souls to take.
